Filtration catalytique. L'oxydation du manganèse contenu dans l'eau peut s'effectuer avec le seul oxygène dissous dans l'eau, à condition de catalyser la réaction; à cet effet on filtre sur un matériau riche en bioxyde de manganèse comme par exemple un minerai de manganèse ou simplement sur un sable recouvert d'une couche de bioxyde de manganèse. 4, record 2, French, - dioxyde%20de%20mangan%C3%A8se
